论文摘要
基于$ su（3）_ {c} \ otimes su（3）_ {l} \ otimes u（1）_ {x} $ gauge组被称为331型号的标准模型的扩展。定义特定331模型的外来光谱的费米分配和电荷等不同的特性，由$β$参数固定。在本文中，我们研究了331个模型的两个版本中的电荷量化，由条件$β= 1/\左（3 \ sqrt {3} \ right）$和$β= 0 $。在这些框架中，例如带有分数电荷的新的瘦素和仪表玻色子。此外，根据版本，出现了非标准的分数电荷甚至中性的夸克。考虑到电荷运算符的定义是歼灭真空的组发电机的线性组合，从拉格朗日的不变性中的经典约束，以及消除量规和混合量规态异常，可以在两种版本中验证电荷的量化。
The extensions of the Standard Model based on the $SU(3)_{C} \otimes SU(3)_{L} \otimes U(1)_{X}$ gauge group are known as 331 Models. Different properties such as the fermion assignment and the electric charges of the exotic spectrum, that defines a particular 331 model, are fixed by a $β$ parameter. In this article we study the electric charge quantization in two versions of the 331 models, set by the conditions $β=1/\left( 3\sqrt{3}\right)$ and $β=0$. In these frameworks, arise exotic particles, for instance, new leptons and gauge bosons with a fractional electric charge. Additionally, depending on the version, quarks with non-standard fractional electric charges or even neutral appear. Considering the definition of electric charge operator as a linear combination of the group generators that annihilates the vacuum, classical constraints from the invariance of the lagrangian, and gauge and mixed gauge-gravitational anomalies cancellation, the quantization of the electric charge can be verified in both versions.
